AUXILIARY CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 755,805, dated March 29, 1904.

T0 aZZ whom it may concern: 7

Be it known that I, JOHN WORTHINGTON SMITH, a citizen of the United States, residing at Ottawa, Ontario, Canada, have invented new and useful Improvements in Auxiliary (Jar-Couplers, of which the following is a specification.

The object of this invention is to provide simple auxiliary coupling devices whereby cars may be quickly and securely coupled when for any reasonfor example, breakage of the knuckle or headtwo couplers of the Master Car-Builders type cannot be properly engaged. Experience shows that with couplers now in use the head is broken more frequently than the knuckle, and in such cases many emergency knuckles are useless. My devices are equally efiective whether the knucklebe broken, the head be split through the central recess, the guard-arm be broken, or the knuckle-bearing projections be injured. Indeed most of the head can be removed and the devices will still work perfectly, for they engage the coupler in the rear of its head.

In the accompanying drawings, Figure 1 is a plan view of my devices applied to a coupler from which the knuckle has been removed. Fig. 2 is a side elevation of the same devices, except the draw-bar and coupler-head, which are not shown. Fig. 3 is an elevation looking from the right in Fig. 2. Fig. 4 is a plan view of a certain yoke member or keeper.

The apparatus consists of a knuckle A and a two-part member by which the knuckle is supported upon a coupler, broken or intact, as the case may be. The knuckle although of one piece has approximately the outline of a closed coupler, being provided witha guardarm A, and is adapted to engage any coupler of the Master Car-Builders type. The upper part of the knuckle-supporting device 1s a member B extending horizontally above and alongside the head E of any coupler to which it is attached. At its forward end it isprovided with a downwardly-extending boss C and at the opposite end with an inturned web D, which may rest uponthe draw-bar E. The web extends downward on each side of the draw-bar as a fork having the lower ends of its branches threaded below the plane of Serial No. 187.649. (N0 model.)

the draw-bar. The lower part of this knucklesupporting device is a member F, provided with an upwardly-extending boss G below and registering with the boss 0 and having apertures to receive the ends of the fork branches. Between the two bosses is mounted'the knuckle, which is provided with heavy shoulders to rest against the bosses and is held in place by a vertical pivot-bolt G, passing through it and through the members above and below. Nuts H are placed upon the bolt and the fork branches to hold the lower member or keeper in place. Usually the keeper is forced upward, so that it clamps the draw-bar rigidly; but whether it does'or not it is obvious that the device cannot slip forward so long as any material portion of the head is'left to project beyond the planes of. the faces of the drawbar and that the device can be mounted upon any coupler of the Master Car-Builders type. When properly mounted, it engages the coupler in the rear of its head and also engages 1. In an auxiliary coupler, the combination with a device adapted to engage a Master (Jar- Builders coupler in the rear of its head and to project forward beyond the head, of a knuckle pivotally connected with the forwardly-projecting portion of said device and adapted to engage couplers of the Master Car- Builders type.

2. The combination with a device adapted to engage the rear side of a coupler-head and project forward beyond the head, of a knuckle pivoted to swing horizontally upon the forwardly-projecting portion and adapted to engage couplers of the Master Car-Builders type.

3. The combination with a member adapted to extend alongside the head of aMaster Car- Builders coupler and by an inturned fork to engage its rear side upon opposite sides of the draw-bar, of a knuckle pivoted to the forward end of said member and adapted to engage Master Car-Builders couplers.

4. The combination with a member adapted to extend alongside the head of a Master Car- Builders coupler and by an inturned fork to engage the rear side of the head, of a knuckle swinging upon a vertical pivot-bolt in the forwardend of said member, a keeper adapted to pass over the lower ends of said bolt and of the fork branches, and means for holding the keeper in position.

5. The combination with the upper knuckle-
